Rock Solid. Light Weight. The Gold Standard of 3D and Target Compound Sights.
Since the release of SHIBUYA’s first compound sight in 2005, the series has evolved through the CPX, CPX2, and CPX3 models. Incorporating continuous user feedback, SHIBUYA has refined operability, precision, and reliability—culminating in the creation of theULTIMA CPX IV.
Every adjustment mechanism and structural detail has been re-engineered from the ground up to deliver smoother, more secure operation. It achieves both the fine-tuning precision demanded by top-level archers and long-term stability that endures years of use.
As the most balanced and versatile model in the CP series, theULTIMA CPX IVcombines exceptional ease of use with outstanding build quality—making it a trusted choice for compound archers of all levels.
Vertical and horizontal adjustments now move approximately0.04 mm per click, an improvement from the previous model’s 0.05 mm. This enables ultra-fine tuning to meet the micron-level precision demanded by competitive archers.
Zero Backlash — ZPE System Integration
TheZPE System, highly acclaimed in the CP PRO and CPX III series, is now adopted in the CP PRO G2 as well. By optimizing the internal structure, true zero backlash has been achieved. Even during reverse adjustments, each click responds firmly, allowing for more accurate sight calibration.
SIGHT SCALE PLATES
Both sides of ULTIMA CPX’s elevation bar feature recessed metal sight scale plates. Each ULTIMA CPX Ⅳ includes a blank plate and reference scale. 8 double-sided sight scale plates, for a total of 16 scale options, are available sold separately. Printed sight tapes can be used on the blank plate supplied.
FLAT SHELF INDICATOR PIN
The flat-shelf indicator pin on ULTIMA CPXⅣ sights is easy to adjust, closer to the sight tape surface than ever before, while still offering enough clearance for layered tapes. Both side pins are locked by a cap screw from the side, preventing accidental movements when locking them down!
TRIA-LOCK SYSTEM
Shibuya’s innovative Tria-Lock system keeps the scope rod approx. 1/2″ closer to the elevation bar than conventional target sights. This significantly reduces moment effected on the windage unit – a significant factor in development of play and faults! The innovative new Tria-Lock system encloses the scope rod holder from three sides, keeping it perfectly aligned and without play to produce a rattle-free, zero-tolerance environment.
X-Lock System US Pat No. 7,287,335
Re-adjustable, zero-tolerance fit between the windage unit and sight frame. Super-slick and durable polyacetal resin guide spacers enclose the elevation rail, re-adjustable at the turn of a set screw. All parts field-adjustable and -replaceable!
